In 2013, it carried approximately 20.7 million passengers and 804 million tonnes kilometers of goods. The company employs 3,090 people, making CFL the country's seventh-largest corporate employer.[2]

The Luxembourg rail system comprises 275 route-kilometres, of which 140 km is double track and 135 km single track. Of the total track length of 617 km, 574 km are electrified. The majority of the electrified track (526 km) is operated at 25 kV, 50 Hz, though some 48 km are run at 3 kV DC.

Luxembourg borders Belgium, France and Germany. Correspondingly, there are cross-border services into these countries. Some are wholly run by CFL, whereas others are run by SNCF, NMBS/SNCB and DB. CFL passenger trains cover the majority of the network.

CFL operates the majority of its passenger trains using EMUs and electric locomotives with push-pull stock. The company also has a fleet of diesel locomotives for hauling freight trains and for general shunting purposes.
